Ramstein and Arégui's imaginative picture book without text challenges young readers to use their skills of deduction. Pairs of pictures demonstrate relations or the passage of time. Some combinations are obvious, such as an acorn and an oak tree or a beehive and a honey pot, some require more thought, as in the pumpkin followed by the horse-drawn carriage, but all lend themselves to discussion. Digital images and muted tones give the book the look of an educational text, but many of the pictures are playful and amusing. This is a book that children will enjoy examining many times, and adults will find a useful teaching tool. A former teacher, Jennifer Minicus is a full-time wife and mother living in Ridgewood, NJ.
